Halloween is — uh, how do you say? — high season for writing about race and culture. The list of celebrities, stores and college freshmen sporting racist costumes — plus the inevitable backlash — means these stories practically write themselves.

This year it was the turn of Ohio University, the University of Minnesota and the University of Colorado, Boulder, which posted this note on its website: "If you are planning to celebrate Halloween by dressing up in a costume, consider the impact your costume decision may have on others in the CU community."

Back in 2010, Burgwell Howard, then dean of students at Northwestern University, sent an email to students that outlined the definition of blackface. Howard asked, "Wearing a historical costume? If this costume is meant to be historical, does it further misinformation or historical and cultural inaccuracies?" (Hampshire College has its own Halloween costume infographic, "Is Your Costume Racist?")

Mistakes don't have to be made.

The New York Times reports you can now turn to "costume concierges" at Ricky's, a New York-based beauty chain that helpfully "steer[s] light-skinned shoppers who want to go as dark-skinned characters to more 'creative cues' other than skin color."

Here's some seasonal badness from people who could have used the advice of a "costume concierge":

People dressing as a bloody Trayvon Martin (and to add insult to injury, in blackface, nonetheless) and George Zimmerman (with a shirt emblazoned with "Neighborhoo Watch" — we're guessing there's a D, though it's not clear if they ran out of consonants).

Folks wearing torn and bloody flight crew and captain outfits, a reference to the Asiana Airlines Flight 214 crash in San Francisco that killed three and injured more than 100. The uniforms even have the infamous and mistaken names — Capt. Sum Ting Wong, Capt. Wi Tu Lo, Ho Lee Fuk — on them.

The crew of Al Jolson wannabes at Milan's "Halloweek" costume party that had a "Disco Africa" theme.

The thing about the annual Halloween costume outrage cycle is that redemption is never far behind for those willing to acknowledge their own mistakes. After protests from an Asian-American civil rights group, Pottery Barn removed its kimono and sushi chef costumes and issued an apology: "We did not intend to offend anyone with our Halloween costumes and we apologize."

You can set your watch to these Halloween WTF moments. What's the best way to curb them? Share your thoughts in the comments.

Maybe one day, the Internet won't be overwhelmed with ill-considered Instagrams or Facebook photos on them. In the interim, we wish we could put lumps of coal in these people's blackface Christmas stockings, but they'd probably just smear it on their faces.

*("Blackface Christmas" is actually kind of a thing. In fact, it's a controversial issue in the Netherlands. Zwarte Piet (Black Pete) is a tradition in which folks don blackface to dress as the "helper" of Santa Claus. Zwarte Piet has its roots in slavery and the colonial era, but has since been spun to say his dark skin color comes from gathering soot as he shimmies down the chimney. In recent weeks, it's become an increasingly tense issue as the U.N. has started questioning its validity, sparking protests in the Netherlands.)
